Sea Side Aquatics 0.75″ Ceramic Coral Frag Plug – Reef-Safe Coral Mounting Plug

About This Product

The Sea Side Aquatics 0.75″ Ceramic Coral Plug is a durable, reef-safe coral frag mounting accessory designed for propagating, growing, displaying, and transporting coral fragments in saltwater reef aquariums. Featuring a porous ceramic construction, textured mounting surface, and convenient stemmed design, this compact frag plug provides a dependable foundation for a wide variety of SPS, LPS, soft corals, and zoanthids.

Coral propagation is an important part of reef aquarium keeping, allowing hobbyists to grow their coral collections, share healthy fragments, and establish new colonies without relying exclusively on wild-harvested specimens. A high-quality frag plug provides a stable mounting surface that helps coral fragments attach, encrust, and develop into established colonies.

The 0.75-inch (3/4-inch) mounting surface offers an appropriately sized foundation for small coral frags while minimizing the space required in frag racks and propagation systems. Its compact design makes it especially useful for maintaining organized coral collections, growing multiple fragments, and displaying newly mounted corals.

Manufactured from porous, aquarium-safe ceramic, these frag plugs offer an advantage over certain cement-based alternatives. According to Sea Side Aquatics, the ceramic material is suitable for immediate aquarium use and does not require extended curing or soaking before installation.

The naturally rough surface provides an excellent bonding area for reef-safe cyanoacrylate gel and suitable coral mounting epoxy. Once secured, coral tissue can gradually spread across the mounting surface, helping create a natural-looking attachment as the frag develops.

Each plug features a stem designed for convenient placement in compatible coral frag racks, propagation holders, and standard egg-crate lighting diffuser grids commonly used in aquarium frag systems. The stem can also help position the coral in openings within suitable aquarium rockwork.

Unlike lightweight plastic frag plugs that may shift under strong water movement, ceramic plugs provide a more substantial mounting foundation while remaining convenient to handle and reposition.

These coral plugs are suitable for mounting a broad range of popular reef aquarium corals, including Acropora, Montipora, Birdsnest, Zoanthids, Palythoa, Kenya Tree, and other compatible small coral fragments.

Whether you’re establishing a dedicated coral frag tank, expanding an SPS collection, organizing a zoanthid garden, or preparing corals for trading and resale, the Sea Side Aquatics 0.75″ Ceramic Coral Plug provides a practical, durable, and reef-safe solution for coral propagation.

Recommended Applications:

SPS Coral Propagation

The 0.75″ Ceramic Coral Plug is ideal for mounting small SPS coral fragments, including Acropora, Montipora, Stylophora, Pocillopora, and Birdsnest.

Its textured mounting surface provides a suitable base for adhesive attachment, while the compact dimensions help maximize available space in dedicated SPS frag racks.

LPS Coral Mounting

Small LPS fragments may be secured to ceramic plugs when the coral’s skeletal structure and growth requirements are appropriate for the mounting surface.

Ensure that larger or expanding LPS corals have sufficient room and are not positioned where they may damage neighboring coral fragments.

Zoanthid and Palythoa Propagation

Ceramic frag plugs provide a convenient platform for mounting Zoanthid and Palythoa colonies.

As the polyps establish themselves, they may naturally spread over the mounting surface, creating attractive miniature colonies.

Exercise appropriate protective precautions when handling Zoanthids and Palythoa, as some species may contain dangerous palytoxin.

Soft Coral Propagation

Suitable soft coral fragments may be mounted using species-appropriate attachment methods.

Some soft corals attach more successfully when temporarily secured with mesh, a container of rubble, or another gentle method rather than glue applied directly to soft tissue.

Frag Tanks and Coral Farms

The compact stemmed design makes these plugs convenient for organizing multiple coral fragments in commercial coral propagation systems, dedicated frag tanks, and hobbyist grow-out setups.

Installation and Usage Instructions:

1. Prepare the Frag Plug

Remove the ceramic coral plug from its packaging and rinse it with clean saltwater or properly prepared aquarium water to remove any loose dust or debris.

The manufacturer’s ceramic material does not require an extended curing period before aquarium use.

2. Select the Coral Fragment

Choose a healthy coral fragment suitable for mounting on a 0.75-inch surface.

Inspect the fragment for pests, damaged tissue, or other concerns before introducing it into a propagation system.

Use appropriate coral handling and cutting procedures for the particular species.

3. Apply Reef-Safe Adhesive

For coral fragments with suitable skeleton or attachment surfaces, apply a small amount of reef-safe cyanoacrylate gel to the mounting area.

Position the coral fragment on the plug and hold it securely until the adhesive begins to set.

Avoid applying adhesive directly to sensitive living coral tissue unless the species and mounting technique permit it.

4. Position the Frag Plug

Place the mounted coral into a compatible frag rack, egg-crate grid, coral holder, or stable opening in the aquarium rockwork.

Ensure the plug is securely supported and will not tip over or become dislodged by water circulation or aquarium inhabitants.

5. Provide Appropriate Coral Conditions

Position each coral according to its specific requirements for lighting, water flow, and spacing.

The ceramic plug itself does not require special lighting or water conditions; the needs of the attached coral should determine placement.

6. Monitor Coral Attachment

Observe the coral as it acclimates to its new mounting location.

With appropriate conditions, many coral species gradually encrust or attach across the ceramic surface.

Avoid unnecessary handling while the coral is establishing itself.

Maintenance and Care Recommendations:

Inspect frag plugs periodically for unwanted algae, accumulated detritus, and nuisance organisms.

Gently remove debris as necessary without damaging attached coral tissue.

Keep frag racks clean and allow sufficient water circulation around mounted fragments.

If a plug is reused, remove old adhesive and biological residue as appropriate, then clean and rinse it thoroughly using methods suitable for reef aquarium equipment.

Never return a plug exposed to household cleaning chemicals or potentially harmful contaminants to the aquarium without appropriate decontamination.

Check mounted corals regularly to ensure they remain securely attached.

As corals grow beyond the plug’s original mounting surface, transfer them to larger rocks, discs, or appropriate aquarium locations when necessary.
